Political Signs
Baltimore County's zoning code still prints a rule requiring political campaign signs to go up no earlier than 45 days before a primary and come down within seven days of an election, but a federal court permanently enjoined the county from enforcing it in 2008. What remains enforceable under the Table of Sign Regulations is a size cap, a height limit, and a ban on placing signs in the right-of-way or on private property without the owner's consent.
